Methods that may be used for the manufacture of a class of chemical compounds known as terpenoid indole alkaloids, including tabersonine and catharanthine are provided. Compositions useful for the synthesis of terpenoid indole alkaloids, including tabersonine and catharanthine are also provided. The provided compounds are useful in the manufacture of chemotherapeutic agents.

Two cell lines of Tabernaemontana divaricata derived from the same suspension culture were compared with respect to their biotransformation capacity. One is a high indole alkaloid-producing culture which accumulated mainly O-acetylvallesamine. The other cell line biosynthesizes terpehoid indole alkaloids in much lower amounts. Both cell lines were cultured in medium containing either conopharyngine, coronaridine, vobasine or tabersonine. Chemical breakdown was followed in fresh and used culture medium in the absence of cell culture. All the alkaloids investigated underwent chemical transformation. Most of the biotransformation products accumulated by the cultures have been reported to occur in intact plants. Since all the alkaloids added were transformed in the same way by both cultures, the two cell lines seem to have the same biotransformation potential.

with expression profiles similar to known terpene indole alkaloid biosynthetic genes. Screening of these candidate genes by functional expression in Saccharomyces cerevisiae yielded a unique P450-dependent enzyme that stereoselectively hydroxylates the alkaloids tabersonine and lochnericine at the 19-position of the aspidosperma-type alkaloid scaffold. Tabersonine, which can be converted to either vindoline
Synthesis of hexacyclic indole alkaloids related to vindolinine by sonochemical cyclization

Upon treatment with sodium in THF under sonication, 19-iodotabersonine underwent cyclization to the vindolinine ring system. The yields and ratio of the diastereomers thus obtained depended on the sonication parameters.
